Final answer:
Rods are cells in the retina of the eye that are responsible for vision in dark or low-light conditions. They are more sensitive to light than cones and are primarily used for peripheral vision and motion detection. Rods do not provide color information, but they allow us to see shades of gray in dim lighting.
